ʻO ke koho ʻana o ka uhi o loko no nā kini tinplate (ʻo ia hoʻi, nā kini kila i uhi ʻia i ka tin) e hilinaʻi pinepine ʻia i ke ʻano o nā mea o loko, me ka manaʻo e hoʻoikaika i ke kūpaʻa o ka kini i ka pala, pale i ka maikaʻi o ka huahana, a pale i nā hopena maikaʻi ʻole ma waena o ka metala a me nā mea o loko. Aia ma lalo nā mea maʻamau a me nā koho pili o nā uhi o loko:
1. Nā mea inu (e laʻa me nā mea inu palupalu, nā wai huaʻai, a pēlā aku)
No nā mea inu i loaʻa nā mea ʻakika (e like me ka wai lemona, ka wai ʻalani, a pēlā aku), ʻo ka uhi o loko he uhi resin epoxy a i ʻole ka uhi resin phenolic, no ka mea, hāʻawi kēia mau uhi i ke kūpaʻa waikawa maikaʻi loa, e pale ana i nā hopena ma waena o nā mea o loko a me ka metala a pale aku i nā ʻono ʻē aʻe a i ʻole ka haumia. No nā mea inu ʻaʻole ʻakika, ua lawa pinepine kahi uhi polyester maʻalahi (e like me ka ʻili polyester).
2. Pia a me nā mea inu ʻona ʻē aʻe
ʻOi aku ka ʻino o nā mea inu ʻona i nā metala, no laila hoʻohana pinepine ʻia nā uhi resin epoxy a i ʻole polyester. Hoʻokaʻawale pono kēia mau uhi i ka waiʻona mai ka kini kila, e pale ana i ka pala a me nā loli o ka ʻono. Eia kekahi, hāʻawi kekahi mau uhi i ka pale oxidation a me ka pale māmā e pale i ka ʻono metala mai ka komo ʻana i loko o ka mea inu.
3. Nā huahana meaʻai (e laʻa me nā sopa, nā mea kanu, nā ʻiʻo, a pēlā aku)
No nā huahana meaʻai momona kiʻekiʻe a i ʻole ka waikawa kiʻekiʻe, he mea nui loa ke koho ʻana i ka uhi. ʻO nā uhi kūloko maʻamau e komo pū me ka epoxy resin, ʻoiai nā uhi composite epoxy-phenolic resin, ʻaʻole wale e hāʻawi i ke kūpaʻa waikawa akā hiki ke kū i nā mahana a me nā kaomi kiʻekiʻe, e hōʻoiaʻiʻo ana i ka mālama lōʻihi a me ke ola papa o ka meaʻai.
4. Nā huahana waiū (e laʻa me ka waiū, nā huahana waiū, a pēlā aku)
Pono nā huahana waiū i nā uhi hana kiʻekiʻe, ʻoi aku hoʻi e pale aku i nā pilina ma waena o ka uhi ʻana a me nā protein a me nā momona i loko o ka waiū. Hoʻohana pinepine ʻia nā uhi polyester no ka mea hāʻawi lākou i ke kūpaʻa maikaʻi loa i ka waikawa, ke kūpaʻa i ka oxidation, a me ke kūpaʻa, e mālama pono ana i ka ʻono o nā huahana waiū a me ka hōʻoia ʻana i kā lākou mālama lōʻihi me ka ʻole o ka haumia.
5. Nā ʻaila (e laʻa me nā ʻaila ʻai, nā ʻaila lubricating, a pēlā aku)
No nā huahana aila, pono e kālele ka uhi o loko i ka pale ʻana i ka aila mai ka pane ʻana me ka metala, e pale ana i nā ʻono ʻino a i ʻole ka haumia. Hoʻohana pinepine ʻia nā uhi resin epoxy a i ʻole polyester, no ka mea, hoʻokaʻawale pono kēia mau uhi i ka aila mai loko mai o ka metala o loko o ka pahu, e hōʻoiaʻiʻo ana i ke kūpaʻa a me ka palekana o ka huahana aila.
6. Nā kemika a i ʻole nā pena
No nā huahana ʻaʻole meaʻai e like me nā kemika a i ʻole nā pena, pono ka uhi o loko e hāʻawi i ke kūpaʻa ikaika i ka pala, ke kūpaʻa kemika, a me ke kūpaʻa wela kiʻekiʻe. ʻO nā uhi resin epoxy a i ʻole nā uhi polyolefin chlorinated i koho pinepine ʻia, no ka mea e pale pono lākou i nā hopena kemika a pale i nā mea i loko.
Hōʻuluʻulu Manaʻo o nā Hana Uhi Kūloko:
• Ke kūpaʻa ʻana i ka palaho: Kāohi i nā hopena ma waena o nā mea o loko a me ka metala, e hoʻolōʻihi ana i ke ola o ka waihona.
• Kāohi ʻana i ka haumia: Hōʻalo i ka hoʻokahe ʻana o nā mea ʻono metala a i ʻole nā mea ʻono ʻē aʻe i loko o nā mea o loko, e hōʻoiaʻiʻo ana i ka maikaʻi o ka ʻono.
• Nā ʻano sila: Hoʻonui i ka hana sila o ka kini, e hōʻoiaʻiʻo ana ʻaʻole i hoʻopilikia ʻia nā mea o loko e nā kumu o waho.
• Ke kū'ē ʻana i ka oxidation: Hoʻemi i ka ʻike ʻana o nā mea i loko i ka oxygen, e hoʻopaneʻe ana i nā kaʻina hana oxidation.
• Ke kūpaʻa wela: He mea nui loa ia no nā huahana e hana ʻia ana ma ke ʻano wela kiʻekiʻe (e laʻa, ka sterilization meaʻai).
ʻO ke koho ʻana i ka uhi kūloko kūpono e hiki ke hōʻoia pono i ka palekana a me ka maikaʻi o ka huahana i hoʻopili ʻia me ka hoʻokō ʻana i nā kūlana palekana meaʻai a me nā koi o ke kaiapuni.
